    Abstract: The present invention relates to a method of converting video data (1) coded according to a block-based coding technique and having a first image format into decoded video data (2) having a second image format. Said method comprises in particular an inverse quantization step (11) able to supply a transformed data error block. It also comprises a filtering/decoding step including the substeps of truncating (21a) a transformed data block, of completing with zeros (21b) the truncated block of transformed data so as to regain a size of the block before truncation, and of inverse discrete transformation (21c) of the block thus supplemented so as to supply a block of decoded filtered data. Finally, it comprises a subsampling step (22) able to supply decoded video data having the second image format. Such a video data conversion method thus allows a large number of format conversions with reduced complexity and good visual quality.
